Good idea but it doesn't work :(
on 7 July 2013
I brought this for my boyfriend, more or less as a joke, the actual product is Ok, if a bit wonky, but there wasn't enough tubing underneath, with made it bend too harshly, thus creating kink, so asir could not get through :( there was also a considerable amount of glue around the tubing which didn't help air flow at all. Maybe with a few tweaks it would be Ok, but I wouldn't expect to pay that much for something you may need to fiddle with.
